Answer:
Step-by-step explanation:
2 = m / 2 - 7
2 + 7 = m / 2
9 = m / 2
cross multiply
m = 9 * 2
Therefore m = 18
Hope u understood and it helped.
So we know 48 are scored collectively between the two teams, let’s call team 3 “x” and let’s call 4 “y” just so it’s easier to visualise:
We are told that x+y=48
And also told y=3x
If we substitute that in we get
X+3x=48
Collect like terms to get
4x=48 then divide by 4 to get
X=12
We now know that team 3 scored 12 goals
And if team 4 scored 3 times as many we can do 3*12=36 so team 4 scored 36
To make sure it’s correct 36+12=48
Hope this helped :)
